Application Note: Brake Master Cylinder Leak Testing
Finding the more subtle leak defects on brake master cylinders can be a challenge. When missed they can lead to warranty or liability risks in the vehicle. Traditional leak systems primarily focus on the decay portion of the signal waveform which is accurate for most decay type defects; however it doesn’t catch the subtle and more significant defects, such as gross leaks, metal debris, cut cup seal, hair in cup seal, etc.
Engine manufactures required a solution for detecting both static (decay) and dynamic (fill) leak defects in order to manufacture the highest quality brake master cylinder. Read our Application Note to learn how Sciemetric solved the problem.
